An incomplete program named w pl java, which must include three methods, is provided. You must implement two methods within the program as described below. The third method, which is a main method, is already written in the program and you can use it to test your program. The two methods you mat inplement are: • find method • Signature: public static vold find(int[] . int x) • Behavior: • Reccives an array of integers a and an integer x • Performs a lincar search on a for x. • If x is in a, print the indexes of the aray slots where x is stored (there may be multiple x's in a) on the screen. • Ifx is not in a, print the message "x does not exist" on the screen. Note that you should not use Java's built-in method. Your program must scan and search the armay. • isPrifie method • Signature: public static boolean isprefix(String s1, String s2) • Behavior: • Receives two strings sl and s2. Assume that length of sl length of s2. • Returns true if sl is a prefix of s2 and returns false otherwise. Note that you should not use Java's built-in method. Your program must determine whether al is a prefix of s2 by comparing characters, one at a time, in the two strings. • Main method The main method is already written in the given file and it is used to test above two methods. Afier completing the above two methods, if you run your peogram, your output mast be: S is in a(0) S is in a(2] 5 is in a(7) se does not exist abc is a prefix of abcde abc is not a prefix of abdef

Write java code that recursively calculates the Sum of the array cells. Program requirements: Create an array named MyArr and initialize it as follow: 19 27 81 243 88 1- Write a method named ArrSum that recursively calculates the Sum of the numbers in the Array and returns the Sum of the numbers. Hint: Method with 1 parameter (the Array) that returns 1 value (the Array's Sum). 2- Write a method named Display that displays the Array contents and Sum of the numbers. Hint: Method with 2 parameters (the Array) and Sum with no returns (void) 3- Your program output format must be the same as the following: =>> Array Summation Array: 31 19 27 81 243 88 100 6 10 5 Sum: 610 =>> End of the Program Documentation / Comments 31 100 6 10 5

In python and include doctring: First, write a class named Movie that has four data members: title, genre, director, and year. It should have: an init method that takes as arguments the title, genre, director, and year (in that order) and assigns them to the data members. The year is an integer and the others are strings. get methods for each of the data members (get_title, get_genre, get_director, and get_year). Next write a class named StreamingService that has two data members: name and catalog. the catalog is a dictionary of Movies, with the titles as the keys and the Movie objects as the corresponding values (you can assume there aren't any Movies with the same title). The StreamingService class should have: an init method that takes the name as an argument, and assigns it to the name data member. The catalog data member should be initialized to an empty dictionary. get methods for each of the data members (get_name and get_catalog). a method named add_movie that takes a Movie…

How is this program written in java?

In java just add code between the comments public class A6 {/*** In this Java file, you will write three methods that will ensure that the calls in the main methods are* properly executed. You do NOT have to change anything in the main() method. You have to write the methods that* will complete the program.** Pay attention to the method name, the method return type, and the method parameters.*/public static void main(String[] args) {/*Your first method will ask user to enter two values and return the exponent where the firstnumber will be the base and the second will be the exponent. Remember to use a mathematical function.If the user enters value 1 as 2 and value 2 as 3, output of your method should be 8 (2 raised to power 3)*/double calculatedExponent = exponentCalculator();System.out.println(calculatedExponent); //this should print out the exponent value/* Your second method will have two parameters. The first is a String and the second is a number. The methodshould return the…
